Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail.

The utility model discloses a pivot 1, two telescopic strut of supporting 1 tip of pivot and two supports 4 of two telescopic strut of difference fixed mounting, pivot 1 relatively telescopic strut rotates to install rolling bearing between the two, thereby reduce the running friction. Fixed cover is equipped with and follows 1 pivoted pneumatic cylinder installation cover 5 of pivot in pivot 1, as shown in figure 3, pneumatic cylinder installation cover 5 have pneumatic cylinder 6 along the even rigid coupling of circumference, 6 quantity of pneumatic cylinder are 8 in this application, 6 free ends of pneumatic cylinder are installed and are supported at the gyro wheel 7 of pipeline butt joint mouth, gyro wheel 7 can roll at the mouth of pipe. As shown in figure 1, the rollers 7 simultaneously abut against the inner sides of the two pipelines to simultaneously clamp the two pipelines, so that the roundness of the two pipelines is improved, and assembly misalignment is reduced. One of them support 4 on fixed mounting have motor base 8, motor base 8 on fixed mounting have with 1 axial unanimous motor 9 of pivot and speed reducer 10, the output shaft of motor 9 passes through the coupling joint with the input shaft of speed reducer 10, the output shaft rigid coupling of speed reducer 10 has disc 11, the even rigid coupling in disc 11 outer fringe has four short shelves poles 13, short shelves pole 13 is unanimous with speed reducer 10 axial, the even rigid coupling in circumference has four long shelves poles 12 near 1 end of the pivot of speed reducer 10 output shaft, long shelves pole 12 is perpendicular with 1 axial of pivot, four short shelves poles 13 and four long shelves poles 12 cross-arrangement to the transmission rotary motion. The roller 7 rotates synchronously with the welding spot in the whole welding process, and the condition that the stagger of each point of the welding spot is reduced to the minimum is fully ensured.

In this application along with the stretching out of pneumatic cylinder 6, flexible branch takes place to stretch out and draw back to pivot 1 height position changes, though pivot 1 height position changes, but do not influence fixed mounting's speed reducer 10 drive pivot 1 and rotate, mainly because the output shaft of speed reducer 10 and pivot 1 between transmit rotary motion through horizontal and vertical crisscross long shelves pole 12 and short shelves pole 13, no matter pivot 1 moves from top to bottom, left and right, do not influence the two transmission moment of torsion, so the two initial installation required precision is very low, the restrictive condition on the assembly is few, especially adapted popularization.

The middle part of the roller 7 is provided with a groove, the position of the groove corresponds to the position of a welding line, and the welding of molten metal and the roller 7 is avoided during welding.

The bottom ends of the two supports 4 are respectively provided with a caster 14, so that the device can slide on the ground and in a pipeline conveniently.

The telescopic supporting rod comprises a rod A2 and a rod B3, the rod A2 is inserted into the rod B3, the telescopic supporting rod automatically stretches out and draws back along with the extension of the 8 hydraulic cylinders 6 to match the height of the rotating shaft 1, and the rod A2 is connected with the rod B3 through a linear bearing, so that the sliding friction between the rod A2 and the rod B3 is reduced.

The hydraulic cylinder 6 is driven by a hydraulic system, which is common knowledge and will not be described again.

To sum up, this application through evenly distributed's pneumatic cylinder 6 from the inside mouth of pipe chucking with two butt joints of pipeline, to two mouths of pipe correction circularities, reduces the butt joint stagger amount to evenly distributed's 6 rotational speeds of pneumatic cylinder are synchronous with welding speed, and the stagger amount of each point of fully guaranteeing the welding seam falls to the minimum. The pipe fitting need not be moved in this application use, only need to put into it to the interface inboard can.
